Today’s Challenge
Our arithmetic and strategy board game, Mathematically Possible, uses three normal dice involving numbers from 1 to 6, but larger numbers can be introduced to the game simply by using special dice, just as in this challenge.
Use the numbers 2, 4 and 10 once each with + – × ÷ available, can you list the 14 target numbers from 1-30 that are mathematically possible to achieve?
The 7puzzle Challenge
The playing board of the 7puzzle game is a 7-by-7 grid of 49 different numbers, ranging from 2 up to 84.
The 3rd & 7th rows contain the following fourteen numbers:
4 11 13 24 25 27 30 36 42 45 66 70 77 80
What is the difference between the two prime numbers listed?
